Part B: Boiling Point Elevation (Sugar in Water) Instructions: 1. Plot the following data on a graph. - X-axis: Molality of Sugar \( \left(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\right) \) - \( Y \)-axis: Boiling point of the solution ( \( { }^{\circ} \mathrm{C} \) ) \begin{tabular}{|l|l|} \hline Molality (m) of Sugar & Boiling Point \( \left({ }^{\circ} \mathrm{C}\right) \) \\ \hline 0.0 & 100.2 \\ \hline 0.2 & 100.4 \\ \hline 0.4 & 101.8 \\ \hline 0.6 & 101.2 \\ \hline 0.8 & 101.6 \\ \hline 1.0 & 102.5 \\ \hline 1.2 & 1024 \\ \hline 1.4 & 103.8 \\ \hline 1.6 & 103.2 \\ \hline 1.8 & 103.6 \\ \hline 2.0 & 104.0 \\ \hline \end{tabular} Questions: 1. True or False: Boiling point increases as molality of sugar increases. 2. Yes or No: Does adding more sugar raise the boiling point of the solution?

Number of hours spent studying: 25 Score obtained in Math Statistics = 8 Procedure Questions: 1. Create a table with the following five columns using the given data. Below the table, create a scatter plot (graph) of all the points. (Do not correct the points) Label the axes properly. You may use Desmos or GeoGebra for this. Solve each question and show your solution. (a) What is Lo? (b) What is Ev? (c) What is Ez? (d) What is Ev? (e) What is Ety? (f) Calculate the correlation coefficient. Show your complete step-by-step solution. Round your final answer to two decimal places. (g) Is the relationship strong, weak, positive, negative, or zero? (h) What is >? (i) What is y? Round your final answer to two decimal places. (j) Suppose the relationship is significant. Calculate the slope of the regression line. Show your complete step-by-step solution. Round your final answer to two decimal places. (k) Calculate the y-intercept of the regression line. Show your complete step-by-step solution. Round your final answer to two decimal places. (l) Find the value of when = 100. Show your step-by-step solution. Round your final answer to two decimal places. Copy the same scatter plot from No and graph the regression line on the same plot. You may use Desmos or GeoGebra for this. Below this new graph, write the equation of the regression line.
